J.J. Abrams confirmed to ET at the Producers Guild Awards that he is working on a Lance Armstrong script, and might be considering Cooper for the lead.

"[Bradley Cooper] sent me an email and we've been talking," Abrams said on Saturday.

According to Cooper, the talks have been very informal.

"[Abrams] and I email all the time, but we didn't say anything specific," Bradley said at Sunday's SAG Awards. "I didn't even know that he had the rights to it ... that's how out of the loop I am."

Paramount Pictures and Bad Robot (J.J. Abram's production company) secured the rights to Cycle of Lies: The Fall of Lance Armstrong, a book proposal penned by Juliet Macur, in mid-January just after Armstrong admitted publicly to doping during all seven Tour de France wins. The author, a sports reporter from The New York Times, has covered the athlete over the span of a decade throughout Armstrong's struggle with cancer, years of doping allegations and ensuing lawsuits.
